Specification of Letters Patent. Patented Aug. 22, 1922.

Application filed November 8, 1921. Serial No. 513,773.

To all whom it may concern:

Be it known that I, FRANK GAMBINO, a citizen of the United States,residing at Philadelphia, in the county of Philadelphia and State ofPennsylvania, have invented new and useful Improvements in CombinationPadlocks, of which the following is a specification.

This invention relates to a padlock, the general object of the inventionbeing to provide a lock of the permutation type, each limb of theshackle being controlled by a series of discs.

Another object of the invention is to form the shackle of two parts, onehalf being permanently but movably connected with the lock case and theother being detachably connected with the first part.

This invention also consists in certain other features of constructionand in the combination and arrangement of the several parts, to behereinafter fully described, illustrated in the accompanying drawingsand specifically pointed out in the appended claim.

In describing my invention in detail, reference will be had to theaccompany ng drawings wherein like characters denote l1ke orcorresponding parts throughout the several views, and in which I Figure1 is an elevation of the invention.

Figure 2 is a sectional view with the lock in open position.

Figure 3 is a plan view of my 1nvent1on with the limbs of the shacklebroken away.

Figure 4 is a sectional view approximately on the line 4 -4c of Figure1.

Figure 5 is a detail elevation of a portlon of the shackle member.

In these views 1 indicates the case which is constructed in two sectionsand secured together by suitable bolts 1. The case 1s provided with theopenings 2, through which the discs 3 extend, and the openings 4: forthe shackle 5. The discs 3 are provided with reduced parts 6 whichengage recesses 7 in the adjacent discs so that said discs are rotatablyarranged one on the other. The reduced parts are hollow so as to formspaces between the discs to receive the projections 8 on the limbs ofthe shackle. Each disc is provided with a key-hole shaped opening beingspaced apart a distance which will permit them to enter the spacesbetween the discs, when the discs are turned and thus lock the two partsof the shackle in closed position. WVhen all the key-hole shapedopenings are in alignment the shackle can be withdrawn though I preferto make the limb 10 of one part of the shackle of greater length thanthe limb 11 of the other part and to so form the opening 4: for saidpart 10 that the first projection on said limb cannot pass through theopening so that this part of the shackle will remain in connection withthe case at all times. The other opening 4 is of key-hole shape so thatthe limb 11 can be withdrawn therethrough. The two parts are connectedtogether by the socket 12 in part 10 receiving the projection 13 in part11 so that when the part 11 is withdrawn from .the case it can be movedlaterally to free it from the part 10. As shown the two sets of discsare arranged one at the lower part of the case and the other at the topthereof and at opposite sides.

From the above it will be seen that the discs must first'be moved into aposition where all the openings are in alignment with each other, thediscs being provided with the usual indicating marks for facilitatingthe positioning of the discs by a person familiar with the propercombination.

It is thought from the foregoing description that the advantages andnovel features of my invention will be readily apparent.

I desire it to be understood that I may make changes in the constructionand in the combination and arrangement of the several parts, providedthat such changes fall within the scope of the appended claim.

What I claim is A lock of the class described comprising a casing havinga pair of openings therethrough and a corresponding number of transversebores communicating with said openings, a series of discs disposed ineach opening and rotatably arranged one over the other, each disc beingprovided with a reduced portion on one side and a recess on the oppositeside, said reduced portion on the intermediate discs being hollow andadapted to engage the recess of the adjacent disc and provide a spacebetween each disk thereby, said discs being provided with a key holeshaped opening centrally arranged therethrough, a tWo part shackle, asocket limb, a plurality of spaced projections arin one part and aprojection in the other for ranged on each limb and adapted to be;reengaging the socket, a pair of limbs deceived in the keyhole shapedopening in 10 pending from said shackle and one limb besaid discs forthe purpose specified.
